Hi Guys,
I have a later model Carrera speedo in my '71 914-6 because my car was at 86,xxx miles when we disassembled it for a full restoration and some minor mods. I did not want to lose the original miles, my speedo/odometer worked when we parked the car and I have paperwork supporting the mileage, so I decided to go with a newer speedo to add the extra digit. Great idea that has turned into a slight problem. I have now bought 3 speedo GPS units and we are still trying to sort this out. The current one, I am not sure of the manufacturer as the shop doing the work purchased and installed it, is working mostly but reading low. They are trying to calibrate it to be accurate and thus far have not got it dialed in. Anyway, I forwarded this thread to them to see if the OP's post might be of some assistance. Thanks and cheers, Michael
